Dear all,
I'm very happy to announce a preliminary support for uploading, visualizing and sharing surface maps in fsaverage space in NeuroVault.org.
The following features are currently supported:
1. Uploading .mgh, .curv, and .gii scalar maps: 2. Visualization of the surface map projected into the MNI volume (using MNI template surface reconstruction instead of fsaverage) 3. Downloading of the maps in GIFTI format (with metadata correction making viewing of the files in both Freeview and Connectome Workbench easy).
Example map: http://neurovault.org/images/31996/
Thanks to the projection to the MNI volume space all of the extra analysis features of NeuroVault (cognitive decoding using neurosynth, gene expression decoding using Allen Brain Atlas data, searching for maps with similar activation patterns) will work seamlessly.
TODO (aka help needed): 1. Improve the surface reconstruction of the MNI atlas (the cortex is too thin in some areas) 2. Provide 3D visualization using brainbrowser 3. Add Connectome workbench scene files and include fsaverage GIFTI surfaces in download packages. 4. Make volume projection asynchronous to improve response time (it takes several seconds to process one map right now leaving the user with no feedback).
Please let me know what do you think! Don't forget to share your maps!
Best, Chris
